CHAIN-SNAP.

SPECIFICATION forming part of Letters Patent No. 459,364, datedSeptember 8, 1891.

Application filed May 25,1891.

To all whom it may concern.-

Be it known that I, SAMUEL E. KELLEY, a citizen of the United States,and a resident of Providence, in the State of Rhode Island, haveinvented a new and useful Improvement in Chain-Snaps and Methods ofMaking the Same, of which the following is a specification.

Heretofore in the manufacture of chainsnaps it has been customary tofold up a strip of sheet metal to form a tube and after cutting off therequired length from the tube so formed soldering the end pieces andring thereto, and it is the object of my invention 'to facilitate themanufacture of chain-snaps and to improve their quality; and to this endmy invention consists in a seamless drawn chain-snap and in the methodof making the same, as hereinafter set forth.

Figure 1 represents a longitudinal section of my improved chain-snapengaged with the click. Fig. 2 represents the sheet-metal blank fromwhich the chain-snap is formed. Fig. 3 represents a section of the cupfirst formed from the blank. Fig. 4 represents the extension of the cup.Fig. 5 represents the extended cup as partly turned in at its open end.Fig. 6 represents the same as completely turned.

In the accompanying drawings, A repre- Serial No. 394,049. (No model.)

sents the completely-formed seamless chainsnap, made from a sheet-metalblank B, which may be drawn by means of the proper dies in cup form, asshown in Figs. 3 and 4, and then having the edge at the open end a ofthe cup turned inward, as shown in Figs. 5 and -6, and after the openend has been thus turned inward so as to form a proper shoulder e toengage with the click 0 the ring or eye D is to be soldered to theclosed end I), thus providing for the attachment of a chain thereto.

The seamless chain-snap so made presents a very desirable and finishedappearance, and can be made with great economy in cost.

I claim as my invention- 1. The described seamless chain-snap, as a newarticle of manufacture.

2. The described method of making chainsnaps, which consists in drawinga sheet-metal blank into an elongated cup form, then turning the edge atthe open end of the cup inward to form the engaging-shoulder for theclick, and attaching a ring or eye to the closed end of the cup, as setforth.
